A drive shaft 91, journaled in suitable bearings provided in the side frames 00-35, is secured to a sprocket 92 driven by an endless chain 93 which leads around a sprocket 94 keyed to a trimmer drive shaft 95. A sprocket 91 is also secured to the shaft 91 to drive an endless chain 98 leading to a sprocket 99 keyed to the shaft 53. To insure against breakage of parts, a friction clutch 100 is preferably interposed between the shaft 91 and sprockets 92 and 91.

' A pair of lug carriers 101-101 are mounted for reciprocal movement along a pair of carrier frames 102-102 which are supported in spaced parallel alignment upon a pair of cross shafts 103-103. Each of the carriers 10! is provided with a lug 105 extending upwardly for engagement with books traveling along the receiving table 2. The shafts 103-103 are journaled on the free ends of rocker links 104 and 104a which are journaled at their inner ends on cross shafts 106-105 secured to the side frames 85-85. An actuating arm 101 is pivotally connected at 108 to the rocker link 104, and has its other end bifurcated at 103 to straddle the shaft 31. A roller 1 1 1 is journaled on the side of the arm 101 for engagement by the cam surfaces 112 of a box cam 113 keyed to the shaft 91.

Rack teeth 114 are formed along the lower edges of the lug carriers 191 for meshing engagement with a pair of planetary gears 116 secured to a shaft- 1 11 which is journaled on the carrier frames 182-102. A pair of sun gears 118-118 are keyed to a shaft 119 which is journaled at its ends in the side frames 86-85. The sun gears 118-118 mesh with their respective planetary gears 113-113. A fan gear 121 is keyed to a crank shaft 122 to drive one of the sun gears 113, and a crank 123 is keyed to one end of the shaft 122 for pivotal engagement with one end of a connecting rod 124 which has its other end pivotly connected to a crank 12% keyed to the shaft 91. As illustrated in Figs. 1, '1 and 11 in the drawings, a hopper D is provided above the inserting mechanism B to receive a stack of books 16 for delivery to the trimming machine C when books are not being supplied from a binder to the transfer mechanism A. The hopper comprises a base 131 secured to the side frames 85-85 to support a plurality of vertically disposed rods 132 defining the sides and one end of the hopper. A pair of gate brackets 133-133 are secured to their respective side frames 85-85 to support and guide a vertically adjustable gate 134. The gate is adjustable vertically by means of a pair of adjustment screws 136-133 jcurnaled on their respective gate brackets 133-133. Bevel gears 131-131 are secured to the upper ends of the adjustment screws INS-436 for meshing engagement with a pair of bevel gears l38-l33 secured to an operating shaft l39 journaled in Operation In the operation of the feed mechanism shown and described, books [6 are delivered tothe delivery table 2 by means of the transfer mechanism, generally indicated at A- The books t are delivered onto the chute 22 for movement by gravity onto the endless conveyor belts M which act to move the books inwardly against the abutment shoulder 58 of the primary stop member 51. During each revolution of the box cam 68, the abutment shoulder 58 is moved upwardly out of engagement with the forward edge of a book by means of the bell crank lever 6-3, connecting link 62 and arm 59. When a book is released by the primary stop member 5?, it moves downwardly between the conveyor belts 251 and the co-acting rolls 32 for delivery onto the conveyor chains 6-8 of the delivery table 2. During forward movement of the endless conveyor chains 6-6, a book is brought into engagement against the abutment flange 12 of the secondary stop member H and is held against forward movement until a set of push lugs it move into engagement against the other edge of the book. The earns 82 and 83 then act against their respective rollers to pivot the stop arms 13-13 upwardly to permit a book to pass under the abutment shoulder 12.

As more clearly illustrated in Fig. 9, the endless conveyor chains 6-6 convey the books It in equally spaced relation to the inserting mechanism generally indicated at B. The lug carriers I l-llll are reciprocated in their respective carrier frames l02-|02 by means of the crank I26, connecting link I24, arm I23, fan gear [2| and gears I I8 and II 6, the latter gears acting through the rack teeth H4 formed on the lower edges of the lug carriers. During rearward movement of the lug carriers lflll0l, the carrier frames [02-402 are disposed in their lower positions to permit the push lugs [-105 to pass rearwardly under a book It. The carrier frames [OZ-I02 are moved upwardly by means of the cam H3 which acts through the roller Ill, actuating arm I01, and rocker links I M and I85 to position the push lugs l05-I 05 behind a book it. Carrier frames l02-IIJ2 are maintained in their raised position during forward movement of the lug carriers ml. The lugs HIE-I05 act to push each book, or set of books, into position to be trimmed by the first knife, or set of knives, provided on the trimming machine C. It will, of course, be understood that the feed mechanism must be operated in timed relation with the trimming machine in order that one book, or set of books, will be delivered to the trimming machine during each cutting cycle of the trimmer.

A supply of untrimmed books may be delivered to the delivery table 2 by means of a hopper D. As illustrated more clearly in Figs. 7 and 11, the hopper may be provided with an adjustable gate I34 to control the movement of books from the lower end of the hopper.
